Abstract (en)
[origin: DE19645150A1] The invention relates to an optical array for symmetrization of the beam of multiple sequentially fixed adjacent laser diodes, their respective output radiation being asymmetrical in relation to a first and a second direction that are perpendicular to each other. A cylindrical lens (3) with sufficient isoplanacy is mounted on the tilted optical axis (z axis), which is perpendicular to the plane predetermined by the two directions (x, y). Said lens collimates and displaces the output beam bundle of the individual laser diodes in the first direction (x). The cylindrical lens (3) is mounted downstream a directional element (4) that deflects the beam bundle of the individual laser diodes (2) in the second direction (y) with different deflecting angles respectively in such a way that the centers of gravity of the individual beam bundles converge at a predetermined spacing. A redirection element (5) is mounted in the spacing behind the directional element (4) which compensates the different deflection angles of the beam bundle to the optical axis (z axis).
